"A social climber with a nose for power", the 26-year-old Duchess was appointed Mistress of the Robes to Queen Victoria in February 1858, resigning in June 1859, when Lord Derby's government fell. Victoria regretted her departure, calling her "a very pleasant, nice, sensible person". The Duchess soon developed close friendships with Edward, Prince of Wales and Alexandra, Princess of Wales. Lady Eleanor Stanley recorded in her diary in 1859 that during a "paper chase", the Duchess caught her hoop while climbing over a stile and was left with the entirety of her crinoline and skirts thrown over her head, revealing her scarlet drawers to the assembled company. The Duc de Malakoff, the French ambassador, is said to have exclaimed "C'était diabolique!" at the sight.
On 22 July 1852, the twenty-year old Louisa was married at Hanover to Viscount Mandeville, eldest son and heir of the 6th Duke of Manchester. Upon his father's death on 8 August 1855, he succeeded his father as 7th Duke of Manchester, and Louisa became Duchess of Manchester. They had five children:
Louisa became estranged from the Duke, and they lived apart for many years. Louisa became the companion of Spencer Cavendish, Marquess of Hartington, and a notable political hostess. The Duke died in Naples on 22 March 1890. On 16 August 1892, at Christ Church, Mayfair, the sixty-year-old Dowager Duchess of Manchester married Lord Hartington, by then the 8th Duke of Devonshire. She thereby became Duchess of Devonshire, with a nickname of the "Double Duchess". After the Duke of Devonshire's death on 24 March 1908, she was widowed for the second time, becoming the Dowager Duchess of Devonshire. On 15 July 1911, at the Sandown Races in Esher Park, the Duchess died after a seizure, aged 79, and was interred at Edensor in Derbyshire.
